| Abstract: | The thermodynamics model of binary eutectic liquid phase line is presented.The single parameter Margules equation is improved and the temperature added to the parameter.The equation parameters are regressed by the experiment values of five group binary system dodecanol-stearic acid,palmitic acid,myristic acid,lauric acid,capric acid and this system phase diagram is predicted.The predicted results indicate that this thermodynamics model can be used to predict the eutectic PCM binary system phase diagram and ... |
